Fix a grub bug

In this article, I will record how to fix the problem that grub can’t find Windows on nvme. So that someday, I can reuse this to help myself.

First of all, install os-prober.

Then, run update-grub or grub-mkconfig. Then you will find that os-prober is not working.

It will print a warning saying like: OS-PROBER will not be executed in order to protect xxx. If you want to know more, please look GRUB-DISABLE-OR-PROBER document to find more information.

Well, only stupid people will do as what the warning says.

For me, I just vim /etc/default/grub and add one line GRUB-DISABLE-OR-PROBER = false in this file.

Then run grub-mkconfig again. This silly problem will get fixed.
